Estonia's road network is small (about 16,600 km of state roads, only one motorway-grade route — the Tallinn ring) but it runs on three rules that catch foreign drivers: dipped headlights are mandatory year-round, day and night, on every road; the alcohol limit is 0.2 g/L (0.2 promille) for everyone with no separate lower tier for novices, but it is enforced aggressively by the PPA with breath tests at random checkpoints; and the speed limit is not a single number — it changes with the season and the time of day, signed locally rather than nationally.
The seasonal swap is the genuine quirk. The Transpordiamet (Transport Administration) raises limits each spring — for 2026 the new regime began on 10 April, covering 497 km of state road: 86.8 km signed at 120 km/h, 331 km at 110 km/h, and 79.6 km of 2+1 sections at 100 km/h.
The winter regime returns around mid-November (2025's switch was 14 November), dropping most of that network back to 100 km/h on 2+1 roads and 90 km/h elsewhere. The Tallinn–Tartu–Võru–Luhamaa highway carries Estonia's only 120 km/h sections (Kuivajõe–Mäo, km 37.9–82.7) and only in daylight; at night it drops to 110 km/h, and through the signed wildlife crossings to 100/90 km/h.
The Tallinn–Pärnu–Ikla (Via Baltica, E67) runs at 110 km/h day / 100 km/h night through Laagri–Ääsmäe and got a new 2+2 carriageway through Pärnu–Uulu (9.8 km) completed in July 2024.
2+1 roads are the local convention worth understanding: a single carriageway alternates which direction owns the overtaking lane every few kilometres, divided by a steel cable barrier. Time your overtake to your zone — there is no shoulder to recover into.
Estonia has no general motorway tolls and no vignette for cars. The road user charge introduced on 1 January 2018 applies only to vehicles over 3.5 t.
From 1 January 2025 the penalty unit (trahviühik) doubled from €4 to €8, and mobile-camera speeding rose from €5 to €7 per km/h over the limit, so old fine tables are out of date. Winter tyres (3PMSF preferred) are mandatory 1 December – 1 March, allowed from 15 October; studded tyres from 15 October to 31 March.
Watch for moose, deer and wild boar at dawn and dusk, especially near Lahemaa and the inland forests — wildlife collisions injure 20–30 drivers a year on roughly 11,000-strong moose population.
